Oy8-E-121525 -2- December 15, 1925. The delivery air should preferably be blown into some sort of trap, but this is a refinement. If you have tested the Stewart tank and had results equal to ours I think you will have lost interest in this device( although theoretically it is better on hills) because of the necessity of some additional suction device. However on looking the thing over you might let us know what you think of it. Oil Aerator. We are installing this on a car which does not have boilers on the intake pipe, and which will be used for short trips all winter, so as to see whether it really has the ability to stop dilution. If it does then it becomes available as a dilution preventative as an alternative to boilers and may be fitted without trouble on all Silver Ghosts of any vintage. It also contains the complete "bypass filter" for the oil which is so desirable in dirt road districts. Will let you know how it works out.
